match the following definitions with the correct term.
a material that does not
lose or gain electrons
the material that causes a
gain of electrons
a loss of electrons
the material that causes a
loss of electrons
a gain of electrons
a reaction where there is a
loss and a gain of electrons

1. reduction
2. oxidation
3. spectator ion
4. redox
5. oxidizing agent
6. reducing agent

Explanation:

1. A spectator ion is an ion that does not participate in the redox reaction (does not lose or gain electrons), so "a material that does not lose or gain electrons" matches 3. spectator ion.
2. An oxidizing agent is a substance that causes another substance to be reduced (gain electrons), so "the material that causes a gain of electrons" matches 5. oxidizing agent.
3. Oxidation is defined as the loss of electrons, so "a loss of electrons" matches 2. oxidation.
4. A reducing agent is a substance that causes another substance to be oxidized (lose electrons), so "the material that causes a loss of electrons" matches 6. reducing agent.
5. Reduction is defined as the gain of electrons, so "a gain of electrons" matches 1. reduction.
6. A redox reaction involves both oxidation (loss of electrons) and reduction (gain of electrons), so "a reaction where there is a loss and a gain of electrons" matches 4. redox.

Answer:

• a material that does not lose or gain electrons: 3. spectator ion
• the material that causes a gain of electrons: 5. oxidizing agent
• a loss of electrons: 2. oxidation
• the material that causes a loss of electrons: 6. reducing agent
• a gain of electrons: 1. reduction
• a reaction where there is a loss and a gain of electrons: 4. redox
